Be it known that 1, WILLIAM F, Goes of Urbana, in the county ofGh'ampaign and State of llllinois, have invented a certain new anduseful Improvement in Locomotit e-Engines, of which improvement thefollowing IS a specification.

My invention, while particularly designed for application in locomotivesoperating in service at railroad terminals, which are generally of thetype known as yard or switching engines, is equally and desirablyapplicable in locomotives used in general road service.-

The growth of cities and the increase of terminal traffic, and thesubstitution of elecltll tric propulsion therefor. which radical change,has, by reason of its high cost of installation and maintenance, thusfar proved too expensive to be generally accepted as a means of removingthe objections I draft appliance, adaptable to application,

without interference with existing accessories, in locomotive boilers ofthe present standard construction, in the operation of which appliancethere shall be attained the substantial advantages of: (a) reducing by amore efi'ective utilization of the draft inducing capacity of theexhaust steam, the back pressure in the locomotive cylinders, andcorrespondingly increasing the efficiency of the propulsive action ofthe steam onthe pistons thereof; (b), reducing the amount of visiblesmoke emitted, by a more perfect contrbl of the draft action; (a),separating solid matter from the smoke, and reventing its discharge fromthe stack, whereby the percentage of dirt which is normally emitted ismaterially reduced; (at) economization of fuel by the utilization ofsolid material which, in ordinary operation, is wasted; (a), efl'ectingthe entire suppression of the noise of the exhaust; (f), insuring moreeflective blower action, when the locomotive is stand-- ing or drifting,and suppressin the noise of the ordinary blower, and; (g providin forthe ready and expeditious removal an replacement of the apparatus, asmay, from time to time, become necessary or desirable for renewal orrepair of its own members or of other accessories of the locomotiveboiler. The improvement claimed is hereinafter fully set forth. p y

Referring descriptively to thespecific embodiment of my invention which is herein exemplified, it isillustrated as applied in a locomotive boiler of the present standard Itype, in which the shell or waist, 1, is traversed by a plurality offiretubes, 2, which extend from a firebox at the rear, which is notshown, to a, smoke box, 4., connected, in

the usual manner, to the shell, 1, of the boiler. The forward end of thesmoke box is closed by a front, 4, haying a door, 4, closing an openingin the front throu h which access is afforded to the interior of thesmoke box, for the insertion and removal of members contained therein,and in the forward portion of the shell, is a superheater header, 5,superheater pipes, 5, steam pipe, 6, etc. The smoke box is supported oncylinder saddles, 7, in the usual manner, and. is provided at top, withthe usual passa e, open to the stack, 8, through which t e waste gasesof combustion are discharged to the atmosphere.

In the practice of m boiler of the type.

above described, the ordinary vertical exhaust pipe, and exhaust tip ornozzle, are substituted by a turbine casing, and a connectedturbo-muflier, the construction :of which, and their relation to thelocomotive cylinders and boiler will now be described. The turbinecasing, 9, is an annular casting, located substantially concentric wlththe cylindrical wall of the smoke box, the rear end of which casting isflanged,'and -1S connected by bolts to the flanged front of a hollowturbo-muffler, 10, which is preferably made in two sections, boltedtogether in its horizontal axial plane, and 1s 1n the form of a frustumof a cone, havlng its smaller end, which is at its rear, slightlybeveled or flared outwardly, as most clearly shown in Fig. 3.- Laterallongitudinal downwardly projecting legs, 10, are formed on theturbo-muffler, and are connected, detachably, as by bolts and nuts, tovertlcal standards, 10 ,,extending longitudinally in r the smoke box andsecured to the cylinder saddles, 7. The smoke box door opening is madeof sufficiently large diameter to enable the turbine casing andconnected turbo-mufsired.

fier to be passed through it, for insertion in, and removal from,operative position as de- An exhaust supply passage, 9, which is open atits lower end, is bolted to the front of the turbine casing, 9, thelower end of said passage being connected to a short curved exhaustconnection elbow, 7, which communicates, in the manner of an ordinaryconformity with the end of the turbo-muffler, as shown in Figs. 3 and 5.

An operating shaft, 12, is journaled in bearings, 10, 10, in theturbo-muffler, 10, and a steam turbine, 13, which may be of any suitableknown and preferred construction, is fixed on the forward end ofsaidshaft. A draft fan, 14, is fixed on the rear end of the operating shaft,and a thrust bearing, 10 is supported on the turbo-muffler, between thejournal bearings, 10, 10.

The journal and thrust bearings are inclosed in a recess formed in acentral supporting standard, 10, cast integral with or secured to, theturbo-muffler, and covered 'by a cap 10, an oil receptacle being therebyformed, to which lubricating material may be supplied through a pipe,19, leading from a source of supply exterior to the boiler. A suitabledrainage port, 10 (one or more) is formed at the larger end of theturbo-mufiler.

Exhaust steam is supplied to the buckets of the turbine, 13, when thelocomotive is running with open throttle, from the connection elbow, 7*,and supply'passage, 9, through a plurality of ports, 13, formed in therear wall of the passage, 9*, and disposed in a circle concentric withthe operating shaft. For the purpose of operating the turbine when itisdesired to increase the draft in periods in which the locomotive isstanding or dripping, a valve controlled blower pipe, 15, is led fromthe steam space of the boiler into the turbine casing, 9, said pipebeing open to the buckets of the turbine throughsupplemental ports, 13,in the rear wall of the passage, 9".

The portions of the smoke box, 4, in front and in rear, respectively, ofthe draft fan, 14:, are separated by a partition or fan housing, 16,which closely surrounds the rear end of the draft fan, and is opencentrally thereto. The fan housing is forwardly curved or inclined, andat its forward end, is inwardly recurved, as shown in Fig. 1, itsinwardly curved portion form- 1 ing a baflle and constituting the wallof an annular peripheral chamber, 16, into which dust or solid matter,discharged from the boiler tubes, is driven by the centrifugal forcegenerated by the revolutions of the draft fan. As will be readilyunderstood, the space .within the smoke of the fan housing, 16, will,when the 1000- motive is in operation, alwa s be subject to pressuregreater than that of the atmosphere and the, space in rear of saidhousing, to pressure less than that of the atmosphere, the difference inpressure being due to the action of the draft fan. A delivery nozzle,16", projects from the lower portion of the chamber, 16, through theshell of the smoke box, and a delivery pipe, 17, leads from said nozzleto any preferred receptacle, which may be the firebox of the boiler, theash pan, or a 'box; or casing from which the delivered solid matter maybe withdrawn from time to time as may be required.

The space between the chamber, 16, and the turbo blower, which is opento that forward of it in the smoke box, may, if rendered desirable byexceptional conditions, or required by legal enactment, be closed by asheet of netting or perforated plate,

' 18, as indicated in Fig. 8.

In the operation. of the appliance, when the locomotive is running understeam, i. e. with its throttle open, all the exhaust steam from thecylinders is delivered to the turbine, 13, which, with the connecteddraft fan, 14, is thereby rotated. The centrifugal actlon of the wingsof the fan, upon the ox, in fronterner/a products of combustion passingout of the tubes of the boiler, draws the gaseous and sol-id matters ofthe products to and through the central opening of the partition, 16,and into the circumferential chamber, 16, thereof. The gaseousconstituents are forced by the fan through the annular space between thewall of the chamber and lltll tion drop to the bottom of the chamber,16,

the turbo-mufiier, into the smoke box space which is forward of thehousing, from which they are continuously discharged to the atmosphere.The dust and solid matter contained in the products of combusfromwhichthey are also continuously discharged through the nozzle, 16", anddelivery pipe,-17. The exhaust steam from the turbine fills the spacewithin the turbomuffler, 10, and'thence esca es, in a quiet continuousoutflow stream t rough the annular discharge. assage between theturbopipe, 15.

mumer and the flange, of the'end plate, 10, to the smoke box, andtherefrom to the atmosphere, through the stack. lit the condition of thefire should be such as torequire artificial draft when there is noexhaust from the locomotive, which is the case when standing ordrifting, the turbine and draft fan are started, at greater or lessspeed as required, by the admission of boiler steam to theturbinethrough the blower Among the operative advantages, the followingmay be noted. The exhausting action of the draft fan upon the productsofcombustion, causes the actual value'of the negative and positivepressures in the smoke box, as measured from atmospheric pressure, to beless than in ordinary"practice. Thus, the reduction of pressure in thespace in rear of the fan housing need be only sufficient to drawtheproducts of combustion through the boiler tubes and the centralopening of the fan housing, and the excess of pressure in the spaceforward of .in creating draft than the'exhaust pipe and,

tip common in present practice, and fromv this fact there results areduction of back pressure in the locomotive cylinders and acorresponding econom v as compared with the present practice.nothermaterial feature of advantage is found in the complete eliminationof the harsh noise of the ordinary exhaust and of the-ordinary blower,

and the minimization of liability to the discharge of smoke, andespecially of solid matter, to the atmosphere, with the capacity of theutilization of, the unconsumed particles of fuel by their return to thefire-box. Again, the operating shaft and its bearings being, whenoperatmg, inclosed in exhaust steam, they are protected fromdeterioration by the action of the high temperature of the frontandgases. The capacity of ready removaland replacement of theturbo-muiiier and .its attachments is also a feature of much practicalvalue, as upon detaching the connections with the exhaust connectionandsupports,-which can be readilyand quickly done, the'turbo-mu'liier andrelated arts can be slid, upon the supports, out of t e smoke box, thusadording ready access to the superheater and front tube sheet wheneverrequired.
